Unity iOS - Wont compile in Xcode

For the past two days I have been trying to figure out how to run my app built in Unity - on my iPhone through XCode. I do have a developers license, but however - Xcode doesn't seem to manage to build my application properly. What I mean by that is that it gets stuck on 'Compiling 137 of 190'. I have also looked at numerous tutorials etc on how to build from Unity to Xcode - and I don't seem to discover any misconceptions of mine.

While building I get many errors (yellow exclamation-mark) telling me that there's lots of unused variables etc, but I am pretty sure that's not the case. I have Xcode 7.0 and Unity 5.2.0. I don't know if this is relevant or not, but I can mention that my Macbook is from the mid 2010, so I don't have the best of RAM and specs, but I doubt this makes me unable to compile Xcode. Especially if it is rather small apps?

I have also set up a provisioning profile, a certificate and all that, so that's pretty much done. Here is a picture of the Log I have from Xcode:

Any help would be much appreciated!

Btw: I have compiled the code in Unity (C#), and I know there is no errors in the code. I don't have any Unity Pro subscription, may that be the case? And to publish apps without a watermark, can I subscribe to regular Unity Pro, or do I need the Unity Pro iOS?

Sorry for all these questions, I am just very overwhelmed by all this confusion with both the Xcode aspect linked with to Unity, and all these settings and certificates etc.
